I’m having unexplained power usage on right branch of my panel; it appears to doubling the load. I ran an experiment today to determine if I could find the issue. I turned off all the breakers in the panel except for 7 (5-240, 2-120) to allow ct on each wire. If I sum all the left individual CT loads equals the branch CT; on the right the branch is twice the individual CT.
Your mains are configured with a 200A and a 400A CT. Perhaps the L1_Right should also be ECS24200?
Thank you. That was the issue.
